Natron

CGRU in Natron consists of Afanasy node (group) and menu items in main CGRU menu.

Afanasy nodes need to render connected Write nodes and to store render settings. You can connect one Afanasy node to other Afanasy node to render other Write node with different settings at the same time. Each connected node will produce a block - an array of tasks (frames) to render. You can specify dependence between connected nodes.

Job (Web GUI)

Afanasy Node

General

../_images/natron_afanasy_general.png
  • Job Name

    Name to add to job or blocks names. If empty, Afanasy node label will be used.

  • Get Frame Range From Project Settings

    Set first and last frames to project settings.

  • First Frame

    First frame to render.

  • Last Frame

    Last frame to render.

  • Increment

    Frames increment step.

  • Frames Per Task

    Number of frames in task.

  • Sequential

    Frames solving method.

  • Send Afanasy Job

    Construct and send job to Afanasy server.

  • Start Job Paused

    Job will be send paused.

Scheduling

../_images/natron_afanasy_scheduling.png
  • Platform

    OS type the job can launch tasks on: ‘Any’ - any OS, ‘Native’ - the same as the script was launched on.

  • Capacity

    Tasks capacity. ‘-1’ - use default value.

  • Max Running Tasks

    Maximum number of running at the same time tasks. ‘-1’ means no limit.

  • Max Tasks Per Host

    Maximum number of running at the same time at the same host tasks. ‘-1’ means no limit.

  • Priority

    Job priority. ‘-1’ - set default priority value.

  • Hosts Mask

    Job will only on hosts which name matches this pattern.

  • Exclude Hosts Mask

    Job will not run on hosts which name matches pattern.

  • Depend mask

    Job will wait job(s) to be done, which name(s) matches pattern.

  • Global Depend mask

    The same, but will wait for jobs from any user.

MultiWrite

  • Connected Nodes Are Independent

    Nodes can run at the same time, they will not wait each other.

  • Wait Whole Frame Range

    Down stream connected node(s) will wait until whole specified frame range will be rendered. If not checked, each frame will be wait only corresponding frame(s) from this node.

  • Force upstream frame settings

    All upstream connected Afanasy nodes will use this node frame range.

Complex Situation

In this example Final Write waits Back and Front precomps to be rendered.

../_images/natron_complex_network.png

Complex Network

First job block from w_final Write node has af_pre.* tasks depend mask. This means that it will wait all Write nodes that connected to af_pre Afanasy group.

Render Selected

../_images/natron_render_selected_dialog.png
  • First Frame

    First frame to render.

  • Last Frame

    Last frame to render.

  • Per Task

    Number of frames in task.

  • Send Job Paused

    Job will be paused.

Setup

If you start Natron from CGRU Keeper all should work automatically.
